It sounds like a Hollywood blockbuster. “Day Zero” is coming to Cape Town this April. Everyone, be warned.
The
government cautions that the Day Zero threat will surpass anything a
major city has faced since World War II or the September 11 attacks.
Talks are underway with South Africa’s police because “normal policing
will be entirely inadequate.” Residents, their nerves increasingly
frayed, speak in whispers of impending chaos.
The reason for the alarm is simple: The city’s water supply is dangerously close to running dry.
If
water levels keep falling, Cape Town will declare Day Zero in less than
three months. Taps in homes and businesses will be turned off until the
rains come. The city’s four million residents will have to line up for
water rations at 200 collection points. The city is bracing for the
effect on public health and social order.
“When Day
Zero comes, they’ll have to call in the army,” said Phaldie Ranqueste,
who was filling his white SUV with big containers of water at a natural
spring where people waited in a long, anxious line.
It
was not supposed to turn out this way for Cape Town. This city is known
for its strong environmental policies, including its careful management
of water in an increasingly dry corner of the world.
But
after a three-year drought, considered the worst in over a century,
South African officials say Cape Town is now at serious risk of becoming
one of the few major cities in the world to lose piped water to homes
and most businesses.
Hospitals, schools and other vital
institutions will still get water, officials say, but the scale of the
shut-off will be severe.
Cape Town’s problems embody one of the big dangers of climate change: the growing risk of powerful, recurrent droughts.
In
Africa, a continent particularly vulnerable to the effects of climate
change, those problems serve as a particularly potent warning to other
governments, which typically do not have this city’s resources and have
done little to adapt.
For now, political leaders here talk of coming together to “defeat Day Zero.”
As
water levels in the dams supplying the city continue to drop, the city
is scrambling to finish desalination plants and increase groundwater
production. Starting in February, residents will face harsher fines if
they exceed their new daily limit, which will go down to 50 litres (13.2
gallons) a day per person from 87 litres now.
World's green city
Just
a couple of years ago, the situation could not have looked more
different here. In 2014, the dams stood full after years of good rain.
The following year, C40, a collection of cities focused on climate
change worldwide, awarded Cape Town its “adaptation implementation”
prize for its management of water.
Cape Town was
described as one of the world’s top “green” cities, and the Democratic
Alliance — the opposition party that has controlled Cape Town since 2006
— took pride in its emphasis on sustainability and the environment.
The
accolades recognised the city’s undeniable success in conserving water.
Though the city’s population had swelled by 30 per cent since the early
2000s, overall water consumption had remained flat. Many of the new
arrivals settled in the city’s poor areas, which consume less water, and
actually helped bring down per capita use.
But the
city’s water conservation measures — fixing leaks and old pipes;
installing meters and adjusting tariffs — had a powerful effect. Maybe
too powerful. The city conserved so much water that it postponed looking
for new sources.
For years, Cape Town had been warned
that it needed to increase and diversify its water supply. Almost all of
its water still comes from six dams dependent on rainfall, a risky
situation in an arid region with a changing climate. The dams, which
were full only a few years ago, are now down to about 26 per cent of
capacity, officials say.
Cape
Town has grown warmer in recent years and a bit drier over the last
century, according to Piotr Wolski, a hydrologist at the University of
Cape Town who has measured average rainfall from the turn of the 20th
century to the present.
Climate models show that Cape
Town is destined to face a drier future, with rains becoming more
unpredictable in the coming decades. “The drier years are expected to be
drier than they were, and the wetter years will not be as wet,” Wolski
said.
As far back as 2007, South Africa’s Department of
Water Affairs warned that the city needed to consider increasing its
supply with groundwater, desalination and other sources, citing the
potential effect of climate change.
Mike Muller, who
served as the department’s director between 1997 and 2005, said that the
city’s water conservation strategy, without finding new sources, has
been “a major contributor to Cape Town’s troubles.”
“Nature
isn’t particularly willing to compromise,” he added. “There will be
severe droughts. And if you haven’t prepared for it, you’ll get
hammered.”
Mistakes
Ian
Neilson, the deputy mayor, said that new water supplies have been part
of the city’s plans but “it was not envisaged that it would be required
so soon.”
Cities elsewhere have faced serious water
shortages. Millions of Brazilians have endured rationing because of
prolonged droughts. BrasÃlia, the capital, declared a state of emergency
a year ago.
Experts say the water shortages in
Brazil, which have affected more than 800 municipalities across the
country, stem from climate change, the rapid expansion of agriculture,
bad infrastructure and poor planning.
Here in Cape
Town, the water shortages have strained political divisions, especially
because much of the responsibility for building water infrastructure
lies with the national government led by the African National Congress.
“The
national government has dragged its feet,” said David Olivier, who
studies climate change at the University of the Witwatersrand’s Global
Change Institute.
The national government controls the
water supply to Cape Town, other municipalities and the province’s
agricultural sector, including the large wine industry east of Cape
Town. In the first two years of the drought, experts say, the national
government failed to limit water supplies to farmers, intensifying the
problem.
But the city made mistakes, too. Last year,
instead of focusing on “low-hanging fruit” like tapping into local
aquifers, the city concentrated on building temporary desalination
units, said Kevin Winter, a water expert at the University of Cape
Town’s Future Water Institute.
“It takes a lot of time
to build desalination modules, three to five years, and at considerable
cost,” Winter said. “They’re even costlier to build during a crisis.”
Neilson,
the deputy mayor, acknowledged that “some time was lost.” The city, he
said, had now “shifted our efforts dramatically.”
The
city is stepping up its efforts to cut consumption. With water and time
running out, Neilson said he was “acutely aware” of needing to scare
people into changing their behaviour without causing them to panic,
adding, “I don’t think we quite got that right yet.”
So far, only 55 per cent of Cape Town residents have met the target of 87 litres per day.
Helen Zille, the premier of Western Cape province, which includes Cape Town, wrote in The Daily Maverick last
week that she considers a shut-off inevitable. The question now, she
said, is, “When Day Zero arrives, how do we make water accessible and
prevent anarchy?”
Unequal
Cutting
back is a difficult message to convey in one of the world’s most
unequal societies, where access to water reflects Cape Town’s deep
divisions. In squatter camps, people share communal taps and carry water
in buckets to their shacks. In other parts of the city, millionaires
live in mansions with glistening pools.
In vast
townships like Mitchells Plain, residents without cars wondered how they
could even carry water containers home from a collection point.
Faried
Cassiem, who works as a cleaner but does not have a car, said his wife
would have to fetch water for his household of eight.
“There
are so many guys just standing around, with no jobs, so I’ll just give
them two rands to carry the water,” he said, referring to the equivalent
of about 17 US cents.
As Day Zero looms, some
were stocking up on water at two natural springs in the city. Others
were buying cases of water at Makro, a warehouse-style store.
In
Constantia, a suburb with large houses on gated properties with pools,
some residents were installing water tanks in their yards.
At
one house, Leigh De Decker and Mark Bleloch said they had reduced their
total water consumption from the city to 20 litres a day, down from 500
litres a day before the drought. Instead, they now draw from two
10,000-litre tanks of treated well water, and were waiting for two
additional tanks to be delivered.
Several weeks before
Day Zero, their use of city water should come down to zero, they said,
estimating that it will cost them about $4,200 to become completely
self-sufficient.
“It allows you to have a certain lifestyle without drawing on resources that other people need,” De Decker said.
